Hi Obi
Welcome.
Yes, it can feel there's a lot of information and it can be quite overwhelming. I do remember feeling like this when I started going through the materials to learn how to improve my relationship with my SO.
I think two things will help you here. First, using self-compassion by not trying to gobble up everything as quickly as possible. Understand that it takes many people a lot of time to understand how this works. Second, exploring the idea of radical acceptance:
